SOLUTION: Can you tell me if I did this right?
Solve each composition and tell whether it is an angle or a ratio:
1. cos(tan^-1(5/12) I got: .923 and that it is a ratio
2. sin^-1(cos(Pi))

Solve each composition and tell whether it is an angle or a ratio:
1. cos(tan^-1(5/12) I got: .923 and that it is a ratio
2. sin^-1(cos(Pi)) I got it is an angle and it doesn't exist.
